Bone Density Study

The technologist will adjust your body and the scanner during the exam.

A bone density study helps diagnose osteoporosis (bone thinning). Scans of your lower back, hip, or forearm are taken to measure the amount of calcium (density) in your bones. Calcium is the mineral that makes up your bones.

Tell the technologist

Tell the technologist if you:

Are pregnant or think you could be

Have any metal in the part of your body being imaged, such as a hip replacement

Have had a recent nuclear medicine scan, CT scan with oral contrast, or an X-ray test with oral contrast, such as a barium enema, barium swallow, or upper GI

Have a severely curved spine, have had spinal surgery, have a history of spinal or hip fractures, or can’t lie on your back

Before your test

Wear clothing without metal closures, such as zippers or metal buttons.

Bring a list of medications that you take.

During your test

You will lie on a table or sit.

Your lower legs may be raised on a platform.

A scanner arm moves back and forth over the part of your body being scanned.

Remain still and do not talk during the scan.

Follow instructions to help prevent the need for a second exam.

After your test

You may need to wait briefly while the images are reviewed.

Your healthcare provider will discuss the test results with you during a follow-up visit or over the phone.
